The Raspberry Pi Foundation has so far concentrated its energy on microcomputers, but now he turns his attention to Arduino-style microcontrollers for your homebrew gadgets. The organization has introduced the Raspberry Pi Pico, a $ 4 card meant to provide a smooth entry point for microcontrollers. Think of it more as a complement to a Pi intended for tasks like analog input.
It’s built on Raspberry Pi’s internal silicon, the RP2040. The ARM Cortex-M0 + dual-core chip, 264KB of RAM and support for 16MB non-flash memory (2MB is onboard) may not seem like much, but it would be powerful for the classroom with strong performance for tasks like machine learning. Most importantly, it’s designed to be flexible – the 30-pin GPIO, USB 1.1 controller (plus USB mass storage mode), and other additions should help it interface with whatever project you’re working on. .
